What kind of medicine should be applied before watering cucumbers in greenhouses, and the cucumber s

Generally, no medication is required. When transplanting and planting, cucumber fertilizer needs a large amount, combined with land preparation, 30-40 quintals of humus miscellaneous fertilizer should be applied per mu, 35-40 kg of imported three-element compound fertilizer, 40 kg of vegetable cake, and 10-15 kg of urea; Reasonable planting, and timely watering of the pressure pocket water, spraying the new high-lipid film 800 times to prevent bacterial infection, improve the ability of seedlings to resist natural disasters, and shorten the seedling period.

Field management, after the end of the seedling period, should be cultivated and weeded in time, supplemented with water and fertilizer, (to achieve "diligent, light, wet"). Spraying to promote the growth of main shoots and promote the differentiation of flower buds. At the same time, before flowering, young fruit stage and expansion stage, Zhuang Guatilin was sprayed to thicken the fruit pedicle to increase the circulating fruit setting rate, promote fruit development, no deformity, no fruit drop, improve the rate of high-quality commodities, increase yield and income.

Prevention and control of pests and diseases, cucumber growth period is prone to powdery mildew, gray mold, blight, aphids and other pests and diseases, should be based on the principle of disease treatment, larval insecticide, and prevention if there is none, timely spraying targeted agents (such as 75% chlorothalonil wettable powder, 10% gram powder, etc.) for prevention and control, and spraying 800 times of the new high-lipid film to improve the efficacy.

No need to spray before watering, planting slow seedlings, after flowering, with 50% carbendazim 500 times and potassium permanganate 1000 times produced in Jiangyin, after mixing, 200ml of root irrigation per plant, has a special effect on wilt and other root diseases, comparable to grafting.

Cucumbers are planted in greenhouses, low temperature and high humidity, gray mold will appear, what drugs are used to control it.

In order to obtain high yield, some cucumber growers will blindly increase the amount of dipping melon and the amount of melon retained, so as to "plunder" the plant nutrition, resulting in the general weak growth of cucumbers, yellowing of leaves, shortening of melon strips, upward movement of melon-bearing parts, and the phenomenon of "seedling" of melon topping in serious cases. If management is not strengthened, the losses will be quite serious.

The cause of cucumber "seedling".

Too much melon left. In order to increase yields, vegetable farmers often take improper measures, leaving all melons that can sit and leaving excess female flowers without removing them.

The harvest was not timely.

Due to the instability of melon prices, sometimes in order to wait for **, the melons that have grown up are left on the seedlings, resulting in "falling seedlings", so that the nutrients in the plant are consumed too much.

Improper fertilization. Many vegetable farmers have the phenomenon of "many, chaotic and miscellaneous" fertilization. In particular, the excessive use of compound fertilizer makes the concentration of soil solution too high, resulting in root damage and weakened absorption capacity, which affects the normal growth of plants.

Overdose. The application interval is short and the concentration exceeds the standard, which is easy to form pesticide damage, resulting in shrinkage of plant leaves and decreased photosynthesis.

Improper watering. Watering does not pay attention to weather conditions, such as cloudy days after watering, it is easy to cause cucumber roots, so that the growth of the root system is inhibited, and the growth of the aboveground part is affected.

Cucumber "breaking" precautions.

Strengthen plant adjustment.

When the cucumber falls on the vine, it can not fall too low at one time, and the plant is held at about a meter height to ensure that the plant has more than 15 functional leaves. For plants with more melons, it is necessary to properly thin the melons, and leave the melons if they are not visible, otherwise it is easy to cause "seedlings break" in the middle and late stages. The yellowing of the leaves at the bottom should be removed in time to reduce nutrient consumption.

Strengthen light management even on cloudy days.

Even after the cloudy day is suddenly clear, the grass can not be uncovered suddenly, and the flowers should be uncovered to avoid causing flashing seedlings.

Pay attention to fertilizer and water management.

In low temperature and low light weather, watering should not be too frequent, and large water should not be flooded. It should also be noted that after watering, the temperature in the shed should be raised to 30 before the air can be released, and the tuyere should be from small to large, and the air outlet should not be too large at one time, so as not to cause flashing seedlings. Fertilizer should be applied with water, and fertilizer containing humic acid or amino acids that is easily absorbed by Huangkuan courgette should be applied, and the one-time dosage should not be too much.

Strengthen disease prevention and control.

Greenhouse cucumbers are prone to downy mildew, brown spot, gray mold, bacterial horn spot, etc., for these diseases, we should adhere to the idea of "prevention first, comprehensive prevention and control" to ensure that there are no susceptible plants in the shed. When using drugs, the concentration should be strictly controlled, and three or five kinds of pesticides should not be mixed to reduce the occurrence of drug damage.

Hit before long.

Because the growth of cucumbers before beating can control its seedling growth too fast, affecting the fruit, if the cucumber grows again, it will affect the growth of cucumbers, so it is best to beat when the seedlings are growing.

Temperature management: Overwintering cucumbers in greenhouses are generally managed from the beginning of the melon period to the depths of winter. At this time, the greenhouse temperature should be flexibly controlled according to the weather changes.

During the day, the temperature is 18 to 20 °C in low light conditions, 22 to 24 °C in medium light conditions, and 26 to 30 °C in strong light; Night 10 18 ° C, not lower than 8 ° C. It is best to keep the temperature difference between day and night above 8°C.

As the plant grows, after removing the old yellow leaves at the bottom, the vines should fall in time so that the leaves are evenly distributed in the space off the ground and in the best light reception and transparency state. The falling vines should be timely, the "faucet" should be avoided from touching the film, and the falling vines should be regularly distributed on the upper part of the ridge to prevent stepping injuries and flooding.

Timely cucumber picking: During this period, cucumbers should be harvested at the appropriate time according to the local market, and the melon picking can be flexibly controlled according to the number of cucumbers available.

Pest control: When overwintering cucumbers grow to this stage, various diseases are prone to occur. Therefore, it is necessary to strengthen the comprehensive control work and extend the planting period of plants.

Summary. Remedial measures after the occurrence of pesticide damage 1, if the leaves are rapidly twisted and drooping, 100 times the sugar solution can be sprayed immediately, and the pesticide damage can be quickly relieved.

2. For the pesticide damage caused by herbicides, if the pesticide damage is not very serious, it can be sprayed with 500 times of anti-disease carb or virus K, and if the growth is seriously inhibited, the drug stock solution can be used to smear the growth point site.

3. For the pesticide damage caused by other pesticides, the following pesticides can be used to alleviate the pesticide damage:

1) Natural brassin, virus K, anti-disease carb, etc.

2) Vegetable Lingjia plant pleiotropin.

3) Foliar zinc sulfate spray 600 to 700 times to promote the production of gibberellin by the plant itself, thereby relieving or alleviating the pesticide damage.

Summary. Cucumber should be treated in time after being damaged by herbicides, if the degree of pesticide damage is low at the beginning, you can quickly spray the foliage of the damaged crop with a large amount of water, and you can mix an appropriate amount of baking soda solution or lime water in the water. Rapid application of fast-acting fertilizers such as urea is then applied quickly to increase nutrients and promote recovery.

After that, it is appropriate to spray drugs that alleviate the damage, such as drugs containing brassinin, indoleacetic acid, sodium dinitrophenol, chlorpyramide and other ingredients.

Hello, I am a little helper of life hs. I'm glad to be able to answer your questions, I have seen your questions, and I am providing you with relevant information for the mu, please wait for 2-3 minutes to touch the defense bell

Cucumber should be treated in time after herbicide damage, if the degree of pesticide damage is low at the beginning, you can quickly spray the foliage of the damaged crop with a large amount of water, and you can mix it with an appropriate amount of baking soda solution or lime water in the water. Rapid application of fast-acting fertilizers such as urea is then applied quickly to increase nutrients and promote recovery. After that, it is appropriate to spray drugs to alleviate the damage, such as drugs containing brassinin, indidole acetic acid, sodium dinitrophenol, chlorpyramide and other ingredients.

Hello, did the above answer solve your problem?

Do you have any other questions about the above answers?

Soybean herbicides affected by the previous year.

Okay, now that you've got the situation, could you wait a moment and find out a new solution for you.

Growth regulators such as brassinin or Shenhong can be sprayed to alleviate the damage of medicine blindness, and at the same time replenish water and fertilizer to promote the recovery of plants and orange growth. When spraying the regulator, you can add some potassium dihydrogen phosphate, urea including some medium and trace elements, and supplement nutrients after resuming growth.

You can try to solve it with this method.

**What about the question、

It is difficult to recover cucumbers that have been damaged by pesticides and are more severe, and the most important measure now is to allow those that have been less damaged by pesticides to recover.

Good. If there are no other problems and mine can help you, please give a thumbs up
